COMBINED LEVELER AND SWEEPER FOR COKE-OVENS.

SPECIFICATION forming part of Letters Patent No. 579,160, dated March23, 1 897.

Application filed August 17, 1895. erial No. 559,661. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN A. MONTGOMERY, a citizen of the United States,residing at Birmingham, in the county of Jefierson and State ofAlabama,have invented a certain new and useful Improvement in a CombinedLeveler and Sweeper for Coke-Ovens; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in a combined leveler and sweeperfor coke-ovens, and has for its object to quickly level the coal thereinand after the coal has been converted into coke and the coke removed tothoroughly sweep and clean the oven, and also to provide a machine whichis simple and inexpensive in construction and very effective inoperation.

My invention consists in the construction and arrangement of the severalparts, as more fully hereinafter described and specifically claimed.

In the accompanying drawings, in which like letters ofreferencedesignate like parts in all the views, Figure 1 is a sectionalview of a coke-oven, showing a side elevation of my improved leveler andsweeper therein, the leveler being applied in full lines and the sweeperapplied as shown in dotted lines. Fig. 2 is a top plan view with theleveler applied; Fig. 3, a detail front view, partly in section, of thesweeper and its operating mechanism and the locking-bolt by which thesweeper is adjusted and held at different composed of hollow tubes orpipes at 5, made preferably plain on its under side for the purpose ofadapting it to be readily manipulated on a suitable support situated inthe door of the coke-oven. At one end these pipes terminate in a handle0, by means of which the apparatus is manipulated in any desireddirection, and at the opposite end terminate in a hollow slotted elbowd.

e is a sprocket-wheel which is mounted on the shaft f and the cogs ofwhich extendinto the slot in the elbow d, and e is a sprocketwheelmounted on the drive-shaft f.

g g are bearings for the sprocketwheels c 6, respectively.

h is an endless sprocket-chain which runs inside the pipes a b (for thepurpose of keeping it from being clogged with dirt, the.) and over thesprocket-wheels.

A series of grooved antifriction-rollers i are mounted at intervals inthe journalsj,formed by cutting the pipes and bending the out portionsoutward.

It is a crank-arm mounted on the end of the drive-shaft f.

Z is a platform mounted on the pipes a b.

M is a suitable engine mounted on said platform, such, for instance, asa hydraulic, steam, electric, or other engine.

"a is the drive-rod of the engine, which is connected to a pin 0 on thecrank-arm 70.

p is a flexible feedwvater pipe for the engine.

C is the leveler, which is provided with a shaft q, having a socket gand set-screw g at its upper end, by which it is attached to the shaft fof the apparatus.

g are scrapers, and g are rakes attached to the hub g at the lower endof shaft q.

The leveler is shown in the drawings with both scrapers and rakes; butwhen desired the rakes may be dispensed with and all scrapers used orthe scrapers dispensed with and all rakes used.

D is the sweeper, provided with a shaft q", connected to the shaft f bymeans of a double screw-threaded nut Q7.

g is a bevel gear-wheel on the lower end of shaft q.

g is a hub or sleeve provided with circular collars (1 and groove Q12are holes in the slot q.

(1 are arms depending from a circular ring which rotates in the grooveand is held at any desired point by means of a spring pressed pinengaging the holes Q12.

g is a chain or rope for operating springpin (115.

is a circular broom having a shaft q", mounted in bearings (1 on thelower end of the arms (1 is a bevel gear-wheel adapted to engage thebevel-gear g and be operated thereby.

Q20 are wheels located on the extreme lower end of the arms Q13, onwhich the sweeper is supported and moved.

E is an antifriction-roller which extends across and is journaled ateach end in the sides of the door-frame, on which the apparatus restsand travels when the leveler is used.

The apparatus may be operated in any direction and the sweeper turned toany angle at the will of the operator.

The operation is as follows: The coke-leveler is inserted through thedoor of the oven and rests and travels on the antifriction-roller E,which extends across and is removably journaled at each end in thedoor-frame. The leveler commences to work on the side of .thecone-shaped pile of coal, and by its circular motion quickly levels thecoal to a uniform level, as shown by the dotted line 1 in Fig. 1. Afterthe coal has been leveled the roller E is removed and the apparatus withdrawn from the oven. The coal is then converted into coke and the cokeremoved by any suitable means. The sweeper is then attached and theapparatus again inserted in the oven and the sweeper worked around, asshown at 50, until the small coke and ashes have been thrown to thecenter. Then the sweeper is changed to the right angle, as shown at 00,Fig. 4, and the apparatus withdrawn from the oven, sweeping and carryingthe material with it through the door to any suitable receptacle.

Having thus described my invention, what I claim is 1. In a portableleveler and sweeper for coke-ovens, the frame having a plain undersurface, and provided on one end with suitable motive power, and on theopposite end with a depending shaft adapted to carry a leveler orsweeper thereon, and means for communicating motion from said motivepower to said shaft, substantially as described.

2. In a portable leveler and sweeper for coke-ovens, the frame having aplain under surface and provided on one end with suitable motive power,and on the opposite end with a depending shaft adapted to receive aleveler said motive power to said shaft, substantially as described.

3. In a portable leveler and sweeper for coke-ovens, the frame having aplain under surface and composed of hollow tubes or pipes,provided onone end with suitable motive power, and on the opposite end with adepending shaft adapted to receive a leveler to level the coke in theoven, and a sweeper to sweep out the oven after the coal has beenconverted into coke and removed therefrom, and means for communicatingmotion from said motive power to said shaft, substantially as described.

4:. In a portable leveler and sweeper for coke-ovens, the frame having aplain under surface, and composed of hollow tubes or pipes provided witha series of antifrictionrollers, sprocket-wheels mounted on shafts atopposite ends thereof, and the sprocket-chain adapted to run inside ofhollow tubes and over the sprocket-wheels and antifrictionrollers, oneof said shafts connected to asuitable motive power by which it isdriven, and the other shaft depending from said frame, and adapted toreceive a leveler to level the coal in the oven, and a sweeper to sweepout the oven after the coal has been converted into coke and removedtherefrom, substantially as described.

5. In a portable leveler and sweeper for coke-ovens, the frame having aplain under surface, and provided on one end with suitable motive power,and on the opposite end with a depending shaft, the leveler mountedthereon and means for communicating motion from said motive power tosaid depending shaft, substantially as described.

6. In a portable leveler and sweeper for coke-ovens, the frame havingsuitable motive power on one end thereof, and the opposite end providedwith a depending shaft, the sweeper mounted thereon, means forcommunicating motion from said motive power to said shaft, and means forsetting said sweeper at different angles, substantially as described.

7. In a portable leveler and sweeper for coke-ovens, the frame havingsuitable motive power on one end thereof, and the opposite end providedwith a depending shaft, the sweeper mounted thereon, means forcommunicating motion from said motive power to said depending shaft andthereby operating the sweeper, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
